This paper compares the mechanical and wear behaviour of LM 24 (Al-Si8Cu3Fe) aluminium alloy that were fabricated using different casting process. The specimens were fabricated using the sand, plaster mold and die casting. For each casting, hardness test and charpy test were performed individually to study the effect of different casting characteristics on the hardness and impact strength. Pin on disc tribometer was used to study the dry sliding wear behaviour for different castings. The results showcased that the hardness, impact strength and wear resistance decreased in the order of die, plaster mold and sand castings. Die cast specimens showed highest hardness (84.87 BHN), high impact strength (2.54J/m2) and low wear rate (0.102 mm3/m) compared to sand and plaster mold cast specimens.
